When referencing a medication, the MedicationRequest resource can either use a code or refer to a Medication resource. This profile sets minimum expectations for the Medication resource to record, search, and fetch medications associated with a patient. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile.

Example Usage Scenarios:

Queries on Medication resource are expected to be within the context of a MedicationRequest resource query. The following are example usage scenarios for the US Core Medication profile:

  • Read Medication resources referenced in MedicationRequest resources.

Mandatory and Must Support Data Elements

The following data-elements must always be present (Mandatory definition]) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each Medication must have:

  1. A medication code

Profile specific implementation guidance:

  • Since the binding is extensible, when a code is unavailable just text is allowed.
  • When the medication is compounded and is a list of ingredients, the code is still present and may contain only the text.
